I'm not sure there is a limit of duration as there is RPM. The bigger the cam the better it will be with more RPM which is where you will run into limitations. Another problem before you would reach the max limitations of the intake/TB would be the PTV clearance and the ability of your springs to maintain the lift that would certainly come with a big duration cam.

Stock ls6 intake is good with a cam that only needs to spin to around 6100 RPMs to make its power.. Anything after that = FAST.
Ls6 intake starts hindering a setup aound 5900 RPMs.
